Interpreting the Response
In EMV 3-D Secure, there are two possible responses:
- Frictionless: No challenge or stepup to the cardholder. While frictionless authentication can indicate a successfully authenticated outcome because the customer's card is enrolled in a payer authentication program, it can also result from the bank failing or rejecting authentication without challenging the cardholder. In the frictionless authentication flow, you receive a PAResStatus of eitherY,A,N,I,R, orUwith an associated ECI value. With successful frictionless authentication, the PAResStatus =YorAand you receive a CAVV. You may also receive a PAResStatus =Iindicating successful authentication but it might not include a CAVV.
- Challenge: The response contains PAResStatus =C. A challenge response has a payload and contains an ACS URL and a StepUpUrl. Challenge the cardholder to provide additional authentication information and display an authentication challenge window to the cardholder so the cardholder can respond to a validation request and receive a validation response.
